Structural contractor recommendations for concrete and steel work

I finally have my drawings done by a structural engineer and am now looking for a structural contractor to do the following work:
1. Dig the basement, replace columns and main girder for steel, install rebars and pour slab and hunch. The method is bench footing, adding 18″ of height.
2. Install C-channels to support the rear bay window and remove the brick under to create a large opening.

Anybody has a contact to recommend to do this type of structural work? The permits are pulled directly by the engineer, so all I need is a company that is reasonable with the price that knows what they are doing and can follow drawings correctly.

Thanks in advance
